I thought the issue i027 was to clarify that - the problem of ordering of messages across Sequences is out of scope for the WS-RX specifications and belongs to the higher up layers. I am not sure if the proposal below adds the intended clarification to the specs. IMHO, the proposal clarifies further the requirements for ordered delivery within a Sequence but it is not saying much about cross-sequence ordering being in or out of scope for the WS-RX specifications.
I was not present on the conf-call when this issue was discussed but here is the cut-paste of the discussion from the minutes:
PZF: I've seen considerable discussion on the mailing list whether this represents correct use of the protocol as designed - I believe the feeling of the TC is to accept the issue and discuss further when we get on to it.
Stefan: Is this an issue of clarity in spec? Or something else?
Andreas: It is about more clarity in spec
Stefan: So, the spec should say "ordering should be enforced within a sequence"? Or specifically state something with respect to the ordering guarantee?
Andreas: It should state the former.
PZF: Are there any objections to accepting this as an issue?
Duane: I have issues with this, but won't hold up the discussion... spanning of multiple sequences, IMHO, belongs to application layer.
Andreas: I agree, but didn't find it very clearly stated in the spec.
Duane: Is this then a proposal to clarify in the spec that the spanning of multiple sequences belongs to the application layer?
Andreas: Yes
PZF: This is an example of an issue which should be written more clearly....
PZF: Any objections to the issue (silence). Issue accepted
ACTION: Andreas to write a clear proposal for this issue.
Thanks,
Sanjay
